Abstract
A substrate treatment device includes a placement platform rotating a substrate, a cooling part supplying a cooling gas to a space between the placement platform and the substrate, a liquid supplier supplying a liquid to a surface of the substrate opposite to the placement platform side, a detector that is above the surface of the substrate and detects a freezing start of the liquid, and a controller controlling the substrate rotation, the cooling gas supply, and the liquid supply. The controller controls at least one of the substrate rotation, the cooling gas flow rate, or the liquid supply rate, and causes the liquid on the substrate surface to reach a supercooled state; and when determining based on a signal from the detector that the freezing of the supercooled liquid has started, the controller starts thawing the frozen liquid after a prescribed interval has elapsed from the freezing start of the liquid.
